Problems solved by technology

[0002] Existing evaporators generally only include heaters and gas-liquid separators. Due to the high viscosity of the evaporated material, it is easy to scale on the wall of the heater tube, resulting in a short service life and poor thermal conductivity, which needs to be improved.

Abstract

A three-phase circulating fluidizing bed evaporator comprises a gas-liquid separation chamber, a solid-liquid separation chamber and a heater. A vapor outlet is formed in the top end of the gas-liquid separation chamber. A liquid material outlet is formed near the bottom end of the gas-liquid separation chamber. A liquid material inlet is formed in the middle of the gas-liquid separation chamber. The liquid material outlet is connected with the heater through a conveying pipeline. A circulating pump is arranged on the conveying pipeline. The heater is connected with the inlet of a solid-liquid separation device through a conveying pipeline. The liquid outlet of the solid-liquid separation device is connected with the liquid material inlet of the gas-liquid separation chamber through a pipeline. A solid recovery device is arranged on the conveying pipeline between the circulating pump and the heater. The solid outlet of the bottom end of the solid-liquid separation device is connected with the solid recovery device through a pipeline.

Description

technical field [0001] The invention relates to the fields of environmental protection waste water treatment, medicine and food, especially evaporation equipment in the case of low flow rate materials for production waste water treatment. Background technique [0002] Existing evaporators generally only include heaters and gas-liquid separators. Due to the high viscosity of the evaporated materials, they are easy to scale on the walls of heater tubes, resulting in short service life and poor thermal conductivity, which need to be improved. Contents of the invention [0003] The invention aims at the deficiencies of the prior art, and provides a three-phase circulating fluidized bed evaporator which has a long service life, effectively prevents fouling of the tube wall of the heater, and effectively improves the heat conduction performance. [0004] In order to realize the object of the present invention, the following technical solutions are provided: a three-phase circula...
